BMW S54B32 engine for sale

BMW S54B32 engine for sale

Product Overview

For sale is a complete BMW S54B32 engine and matching ZF 6-speed manual gearboxfrom a 2006 BMW Z3 M Roadster, recording just 9 kilometres — effectively brand new, from the final production year of the Z3 M Roadster. Both units are from the same vehicle, at the same mileage, and are supplied together with all ancillaries listed — including the Siemens control module, complete wiring harness, and exhaust manifolds.

The S54B32 is the 3.2-litre naturally aspirated inline-six regarded by many as the finest naturally aspirated engine BMW M GmbH has produced — producing 343 horsepower and 365 Nm from a high-revving, Double-VANOS equipped unit that remains the reference point for driver-focused inline-six character. At 9 kilometres, every component of both the engine and gearbox is in factory-new condition.

About the BMW S54B32 and the Z3 M Roadster

The BMW S54B32 is the naturally aspirated 3.2-litre inline-six developed by BMW M GmbH as the successor to the S50 and S52, and is widely regarded as the definitive expression of BMW’s naturally aspirated performance inline-six philosophy. Producing 343 hp at 7,900 rpm — with a redline of 8,000 rpm — the S54 achieves its power through precision rather than forced induction: individual throttle bodies, an 11.5:1 compression ratio, and the Double-VANOS system that provides variable valve timing on both intake and exhaust camshafts across the entire rev range.

The BMW Z3 M Roadster in its 2006 final-year specification is one of the most collected and sought-after M cars of the modern era. The Z3 M Roadster was the last application of the S54 before it was discontinued, and 2006 marked the final year of Z3 production altogether — making 2006 Z3 M Roadster cars the last of their kind and already commanding strong collector values. A drivetrain package — engine, gearbox, ECU, and harness — from a 2006 Z3 M Roadster at 9 kilometres is not simply a set of used parts. It is a historically significant, provenance-confirmed component group from a car whose production ended nearly two decades ago.

The S54 has also been used in the E46 M3 and the Z3 M Coupé — owners of both platforms with confirmed S54 installations may find this drivetrain package compatible with their application, subject to verifying the specific fitment requirements of their chassis.
